I would have thought this requires a market announcement since this half years profit just dropped by the projected 31 December balance of unused credits - probably $400m or so!

Media Release from QAN

The Qantas Group will remove the expiry date on COVID travel credits[1] that were due to run out at the end of this year.Following this decision, Qantas customers with COVID credits can request a cash refund[2], and Jetstar customers can use their COVID vouchers for flights, indefinitely.Today’s announcement makes Qantas’ COVID credit policy one of the most flexible of any airline in the world, and it follows three prior deadline extensions. Some airlines have already expired their travel credits and many more run out completely at the end of this year.To encourage more people to reconnect with their credits, from 4 September 2023 Qantas is offering double the standard number of Frequent Flyer Points for any flights booked with a Qantas COVID credit before 31 December 2023. Due to system limitations, Qantas COVID credit can’t be converted into a travel booking after this date, but can be taken as a refund at any time.The Qantas Group will continue its regular reminders to those customers who still hold COVID credits, including emails, text messages, phone calls and advertisements. Qantas is also working with travel agents to coordinate refunds for travel not booked directly through the airline[3].
